PV flush downleads

lyledunn

New 3-storey house. PV panels on roof and inverter in garage on ground floor. Not unreasonably the client wants the downleads flush mounted. The proposal was to flush mount them in the masonry walls in steel conduit for the route from the loft area, down through bedroom on the top floor and TV room on first floor to garage on ground. No through boxes or the like to indicate cabling below. This is not a one-off situation as the client has a site of 40+ units. Done carefully, I can’t see too much of an issue but I just feel a tad uncomfortable. Any views?

    Caution on cutting vertical chases, Building Regs Part A Structure 2C30

    "Chases:

    a) vertical chases should not be deeper than 1/3 of the wall thickness or, in cavity walls, 1/3 the thickness of the leaf

    b) horizontal chases should not be deeper than 1/6 the thickness of the leaf of the wall

    c) chases should not be so positioned as to impair the stability of the wall, particularly where hollow blocks are used."

    if anywhere near these dimensions, check with architect/structural engineer. You wouldn't want 40+ claims on your insurance
